Abstract

Se describe un sistema de drenaje para usarse con un ajustador de desapretado para un mecanismo de maniobra de freno de ferrocarril en donde el ajustador de desapretado incluye un alojamiento de resorte principal, un alojamiento de tuerca de cono que circunscribe un área de operación critica del ajustador de desapretado, y un alojamiento de desplazamiento excedente. El sistema de drenaje incluye por lo menos una abertura que se extiende a través de una porción de pared lateral del alojamiento de resorte principal. La abertura está configurada para permitir que el fluido y/o contaminantes drenen a través de la misma para reducir la exposición del área de operación critica del ajustador de desapretado al fluido y/o contaminantes. Se puede proporcionar un sello/cubierta de salpicado en la intersección del alojamiento de resorte principal y el alojamiento de tuerca de cono para evitar que el fluido y contaminantes entren al interior del alojamiento de tuerca de cono.
